Default Why does my hot water heater have a blower on top of it?

The home I recently bought has a hot water heater that is different
from any I've ever seen before. There is a fan blower on the top of
it, so that every time the hot water heater kicks on, so does the
blower. Seems odd to me. Hot air rises. But I do notice that the
exhaust is out the side of the house about rather than through the
roof. Is that why? Thanks.


High-efficiency units need fan-forced exhaust because the exhaust temperature
is too low for exhaust gases to be adequately removed by convection alone.
